delphi - FMX shape components does not correctly displayed on the Android platform -

as can see, shape components normal display on windows platform, smooth (including lines, corners , gradient effect).

but on android platform, unacceptable results: lines no longer smooth, corners cannot been closed, gradients become black.

how happen? , how prepare it?

here .fmx file content:

i believe in docs says gradients on strokes (lines) not work on windows 2d rendering. wasn't able find says however. if want windows version utilize 3d can do:

initialization fmx.types.globalusegpucanvas := true;

you can turn on multisampling overriding rendering parameters. lastly can utilize native android component native drawing if need it.
